Description

  The present invention relates to the field of communication technology, and in particular, to a communication method and a communication apparatus.

  The current wireless access method is limited only to the conventional cellular band access. In this case, the communication frequency band of the current wireless access method is less than 2.6 GHz, and the base station (full name in English: Base Station) , Abbreviated as BS) and mobile stations (complete name in English: Mobile Station, abbreviated as MS), and between BSs and between MSs using the broadcast method. Features a coverage area. The same sector can be thought of as one beam, and the MSs covered by that beam share bandwidth by occupying different frequencies, the more MS covered by that beam, the more bandwidth each MS occupies And the capacity of each MS is reduced, and the size of service data transmitted by the user is greatly limited.

  With the development of network technology, it is certain that human society will face the next wave of digital society. For example, 5G wireless networks need to meet the requirement of larger and faster capacity increase, which requires more new frequency band allocations. Extensive research on high-frequency technology has confirmed that the loss of high-frequency communication in some channels is within the acceptable range for communication. Therefore, the data capacity can be increased thanks to the wide bandwidth in the high frequency band from 6 GHz to 300 GHz. Since the high frequency band is characterized by a narrow beam and focused energy, the energy loss caused by reflection or diffraction or transmission to some object is relatively small and the signal quality requirements can still be met. High-frequency wireless communication is already an inevitable flow for future wireless communication development.

  In the prior art, between the BS and the MS, between the BS and between the MS, only the optimum quality channel is searched and used, but the high frequency communication is performed using only one beam, The transmission capacity of the system is still limited.

  DESCRIPTION OF EMBODIMENTS The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Of course, the described embodiments are merely some of the embodiments of the present invention, not all. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

  The receiver in the embodiment of the present invention may refer to a base station (full name in English: Base Station, abbreviated as BS) or a mobile station (full name in English: Mobile Station, abbreviated as MS). The transmitter may also be an MS or a BS, and communications in the embodiments of the present invention include, but are not limited to, communications between BSs, between BSs and MSs, and between MSs. . The MS includes user equipment (complete name in English: User Equipment, abbreviated UE).

  Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a communication device according to an embodiment of the present invention. The apparatus in this embodiment of the present invention is particularly applicable to a communication device that can be used as a receiver, for example, a base station. Specifically, the apparatus may include a first confirmation module 10, a second confirmation module 20, and a communication module 30.

  The first determination module 10 is configured to determine a primary communication path to the target transmitter according to the first SRS when the first sounding reference signal SRS is received, and the target transmitter is configured to It is a transmitter which transmits.

  In a specific embodiment, a transmitter, eg, a UE, can be connected using a wide angle beam to ensure normal communication. The connection process using the wide-angle beam is the same as the connection process using the conventional wireless cellular communication, and details are not described here. Specifically, a sounding reference signal (sounding reference signal, abbreviated as SRS) transmitted by a target transmitter, for example, a newly connected UE, using a wide-angle beam spread over the entire area, that is, the first If an SRS is received, the first determination module 10 may be activated to determine the primary communication path between the UE and the current receiver or BS.

  The primary communication path can also refer to a communication path used during connection by conventional wireless cellular communication, that is, a communication path having an optimum channel quality. Generally, the primary communication path is a prospect (full name in English: Line of Sight, abbreviated LoS) channel. If there is no LoS channel, or in some very special cases, the quality of the LoS channel is inferior to the quality of the non-line-of-sight (non-Line of Sight, abbreviated NLoS) channel, the primary communication path is NLoS channel.

  In some cases, the method in this embodiment of the present invention can be implemented by using the millimeter wave band as a communication frequency band. Millimeter wave refers to a high frequency band from 30 GHz to 300 GHz and has a relatively strong directivity as well as a narrower focused beam. Therefore, higher antenna gain can be obtained by performing communication using millimeter waves. In addition, since millimeter waves are characterized by focused beam energy, energy losses on the reflection and diffraction paths are relatively small. Therefore, millimeter waves can be used for communication.

  The second determination module 20 acquires the identifier of the transmitter that performs communication using the primary communication path determined by the first determination module 10, and determines the secondary communication path of the transmitter indicated by each identifier. Composed.

  After the first determination module 10 determines the primary communication path corresponding to the target UE, the second determination module 20 determines the identifier corresponding to the UE in the beam on the primary communication path between the UE and the current BS. Acquisition, that is, an identifier of a UE that performs communication using a primary communication path may be acquired, and a secondary communication path, that is, a communication path having an optimum channel quality other than the primary communication path may be determined for each UE.

  In a specific embodiment, after connecting the target UE by conventional wireless cellular communication, the BS corresponding to the target UE, i.e. the current receiver, splits the wide angle beam into narrow beams and thus the user is split. In order to control and improve user capacity and system capacity, the respective areas for the secondary communication path corresponding to the UE may be further searched. Specifically, the secondary communication path may be an NLoS channel in a general case.

  The communication module 30 is configured to communicate with the transmitter according to the primary communication path determined by the first determination module 10 and the secondary communication path determined by the second determination module 20.

  In a specific embodiment, the communication module 30 may communicate with UEs in the beam on the primary communication path according to the established primary communication path and secondary communication path corresponding to the UE in the beam on the primary communication path.

  By implementing this embodiment of the present invention, a primary communication path for communication between the current transmitter and the target transmitter is determined according to the SRS signal received by the receiver, and communication is performed using the primary communication path. A secondary communication path is established for each transmitter to be performed, and as a result, communication with each transmitter is performed based on the primary communication path and the secondary communication path, thereby effectively improving the transmission capacity of the system. it can.

  Referring to FIG. 2, FIG. 2 is a schematic structural diagram of another communication apparatus according to an embodiment of the present invention. The apparatus in the present embodiment of the present invention includes the first determination module 10, the second determination module 20, and the communication module 30 of the communication device. Furthermore, in this embodiment of the invention, the first determination module 10 specifically includes a direction determination unit 101 and a narrow beam narrowing unit 102.

  The direction determination unit 101 is configured to determine an optimal arrival direction according to a predetermined determination rule when the first SRS is received.

  The first SRS is transmitted by a target transmitter, for example, a newly connected UE, using a wide-angle beam that is spread over the entire area.

  When the direction determination unit 101 receives the SRS signal transmitted by the target UE using the wide-angle beam that is spread over the entire area, that is, the first SRS, the direction determination unit 101 sets in advance the direction from which the SRS signal has just been received. According to the determined rule, the optimal arrival direction can be determined, and position information regarding the optimal arrival direction can be returned to the newly connected UE. The preset decision rules may be formed according to a specific algorithm and specific criteria. For example, the direction determining unit 101 obtains a signal-to-interference plus noise ratio (abbreviated as SINR) value corresponding to all directions in accordance with the SRS signal in all directions, Of these, the direction corresponding to the maximum SINR value may be selected as the optimum arrival direction.

  The narrow beam unit 102 is configured to narrow the wide-angle beam used by the target transmitter in the optimum arrival direction determined by the direction determination unit 101, and to determine the communication path on which the narrow beam is placed as the primary communication path. The

  After the direction determination unit 101 determines the optimum arrival direction, the narrow beam narrowing unit 102 can narrow the wide-angle beam used by the UE in the optimum arrival direction. For example, the beam narrowing unit 102 controls related beam control modules such as a precoding precoding adjustment module and a beamforming beamforming module to narrow the beam in the optimal direction of arrival. Furthermore, the UE that transmitted the SRS signal after receiving the information related to the optimal arrival direction and returned by the BS, i.e., the target UE, has an associated beam configuration module such as a precoding precoding adjustment module and a beamforming beamforming module. In order to control and obtain a primary communication path between the current BS and the target UE, the beam can be narrowed in the optimal arrival direction.

Furthermore, in this embodiment of the invention, the second confirmation module 20 is
Configured to acquire the identifier of the transmitter that performs communication using the primary communication path and to determine the secondary communication path of the target transmitter according to the second SRS transmitted by the target transmitter corresponding to the target identifier in the identifier The first route acquisition unit 201, the target identifier is the identifier of the target transmitter, the first route acquisition unit 201,
A second path acquisition unit 202 configured to determine a secondary communication path of a transmitter indicated by another identifier in the identifier;
Can be included.

  The second SRS is an SRS transmitted by a transmitter using a narrow beam spread over the entire area.

  After acquiring the primary communication path between the current BS and the target UE by confirming, the first path acquisition unit 201 may acquire the secondary communication path of the target UE, and the second path acquisition unit 202 The secondary communication path corresponding to another UE sharing the primary communication path is extracted, and all UEs performing communication using the primary communication path, that is, all UEs in the beam on the primary communication path are supported. A secondary communication path may be determined. Another UE that shares the primary communication path is a UE that already exists in the beam on the primary communication path, and may record and store the secondary communication path between the existing UE and the current BS. Furthermore, when determining the secondary communication path of the existing UE, the second path acquisition unit 202 only needs to extract the recorded and stored secondary communication path.

  Further, in some cases, the first route acquisition unit 201 may include a determination subunit 2011 and an update subunit 2012.

  The decision subunit 2011 receives the second SRS transmitted in the target direction using the narrow beam deployed by the target transmitter in the entire area, and obtains the channel quality in the target direction by calculation according to the second SRS. And configured to determine whether the channel quality is higher than the channel quality corresponding to the previously established secondary communication path.

  When the decision subunit 2011 receives the SRS transmitted using the narrow beam that the target UE has deployed over the entire area, that is, the second SRS, the decision subunit 2011 calculates the channel quality in the current direction according to the SRS, and calculates After obtaining the channel quality in the current direction by comparing the channel quality in the current direction with the channel quality obtained by calculation at the previous time point, the channel quality in the current direction is obtained by calculation at the previous time point. May be detected.

  The update subunit 2012 determines that the determination result of the determination subunit 2011 is that the channel quality is higher than the channel quality corresponding to the previously determined secondary communication path, the secondary communication path corresponding to the target direction is secondary It is configured to update to the communication path.

Update subunit 2012
If the determination result of the determination subunit 2011 is that the channel quality is higher than the channel quality corresponding to the previously determined secondary communication path, whether the communication path corresponding to the target direction is the primary communication path If the communication path corresponding to the target direction is not the primary communication path, the channel quality of the communication path corresponding to the target direction is higher than the preset communication service quality QoS threshold. If the channel quality of the communication path corresponding to the target direction is higher than the QoS threshold, the communication path corresponding to the target direction may be specifically configured to be updated to the secondary communication path.

  If the decision subunit 2011 detects that the channel quality in the target direction, i.e., the current direction is higher than the channel quality obtained by calculation at the previous time, it means that the communication path corresponding to the current direction is the current BS. It shows that it can update to the secondary communication path | route between target UEs.

  Furthermore, before updating the communication path corresponding to the current direction to the secondary communication path between the current BS and the target UE, the channel quality in the current direction is higher than the channel quality obtained by calculation at the previous time point If detected, it may further be detected whether the communication path corresponding to the current direction is the primary communication path between the current BS and the target UE. When the communication path corresponding to the current direction is not the primary communication path, the communication path corresponding to the target direction is updated to the secondary communication path.

  Furthermore, when it is detected that the communication path corresponding to the current direction is not the primary communication path between the current BS and the target UE, the channel quality of the communication path corresponding to the current direction is set to a predetermined service quality ( Whether it is higher than a threshold in English (full name: Quality of Service, abbreviated QoS) may be further detected. When it is detected that the channel quality of the communication path corresponding to the current direction is higher than the QoS threshold, the communication path corresponding to the current direction may be updated to the secondary communication path. The QoS threshold may be set according to specific channel quality requirements, which is not limited in this embodiment of the invention.

  Specifically, the target UE changes the beam direction according to a preset time interval, uses the corresponding direction acquired after the beam direction has changed as the target direction, and uses the narrow beam deployed throughout the target direction. Send SRS to The decision subunit 2011 receives the SRS transmitted by the target UE in the target direction, and calculates the channel quality in that direction until the first route acquisition unit 201 completes the detection of the SRS transmitted by the target UE in all directions. And the determined secondary communication path is used as the secondary communication path between the current BS and the target UE.

  In addition, in some cases, determining the secondary communication path corresponding to the target UE can be achieved by calculating and comparing in all directions after the BS receives the SRS transmitted in all directions using the narrow beam deployed by the UE. Channel quality is acquired, and the communication path corresponding to the direction with the optimal channel quality (meeting a preset QoS threshold) out of the channel quality in all directions other than the channel quality in the direction of the primary communication path corresponds to the target UE The secondary communication path to be selected may be selected directly.

Furthermore, in this embodiment of the present invention, the device is

May further be included.

Insert module is
Insert the third SRS directly in the uplink subframe or wrap the third SRS in a specific subframe and then insert the specific subframe in the uplink subframe In particular, it is configured to insert a specific subframe within the downlink subframe after wrapping the third SRS, or at a place where the downlink subframe and the uplink subframe are switched.

  The third SRS is obtained by the current BS (ie, the receiver) according to the SRS information returned by the corresponding UE.

  In a specific embodiment, the frame format is determined according to a secondary communication path corresponding to a UE in the beam on the primary communication path, and then a communication path for transmitting uplink and downlink subframes is determined, As a result, communication between the BS and the UE in the beam on the primary communication path is performed.

  After determining the primary communication path for communication with the UE that transmits the SRS according to the received SRS by implementing this embodiment of the present invention, the current BS further determines the secondary communication path for the UE, Extract the secondary communication path of another UE in the beam on the primary communication path, and communicate with each UE in the beam on the primary communication path based on the communication scenario established according to the primary communication path and the secondary communication path As a result, the data transmission throughput and data transmission efficiency of the system can be effectively improved.

  Referring to FIG. 3, FIG. 3 is a schematic interaction diagram of a communication method according to an embodiment of the present invention. This embodiment of the present invention will be described using communication between a BS (ie, a receiver) and a UE (ie, a transmitter) as an example. Specifically, the method includes:

  S301: The target UE transmits an SRS using a wide-angle beam spread over the entire area.

  S302: The BS determines the primary communication path according to the SRS.

  In a specific embodiment, the UE may be connected using a wide angle beam to ensure normal communication. The connection process using the wide-angle beam is the same as the connection process using the conventional wireless cellular communication. Specifically, when the target UE, for example, a newly connected UE receives an SRS transmitted using a wide-angle beam spread over the entire area, the current BS is started and primary communication between the current BS and the UE The route can be determined.

  In any implementation scheme, when the primary communication path between the BS and the target UE is determined in this embodiment of the present invention, an optimal arrival direction is determined according to the received SRS to determine the primary communication path. Can be done. The SRS is transmitted by a target UE, for example, a newly connected UE, using a wide-angle beam spread over the entire area.

  Specifically, when the current BS receives an SRS signal transmitted by the target UE using a wide-angle beam that has been developed over the entire area, the current BS follows the predetermined decision rule from the direction in which the SRS signal has just been received. The optimum arrival direction can be determined, and the position information related to the optimum arrival direction can be returned to the newly connected UE. The preset decision rules may be formed according to a specific algorithm and specific criteria. For example, the BS may acquire SINR values corresponding to all directions in accordance with SRS signals in all directions, and may select the direction corresponding to the maximum SINR value among the SINR values as the optimum arrival direction.

  After the optimum arrival direction is determined, the BS and the UE can narrow the wide-angle beam used by the UE in the optimum arrival direction. For example, the BS and UE control related beam control modules such as the precoding precoding adjustment module and the beamforming beamforming module to narrow the beam in the optimal direction of arrival, and the narrowed beam is the distance between the current BS and the target UE. The communication route arranged as the primary communication route between is determined.

  S303: The target UE schedules another sub-array and transmits an SRS using a narrow beam spread over the entire area.

  S304: The BS determines a secondary communication path that can be used by the target UE according to the SRS.

  After determining the primary communication path of the target UE, in order to determine the secondary communication path of the UE indicated by each identifier, that is, the communication path having the optimum channel quality other than the primary communication path, between the target UE and the current BS The identifier of the UE that performs communication using the primary communication path, that is, the identifier corresponding to each UE in the beam on the primary communication path may be acquired.

  In a specific embodiment, after connecting the target UE by conventional wireless cellular communication, the BS corresponding to the target UE, i.e., the current transmitter, also splits the user so that the wide-angle beam is split into narrow beams. In order to control and improve user capacity and system capacity, the corresponding area for the secondary communication path corresponding to the UE may be further searched. Specifically, the secondary communication path may be an NLoS channel in a general case.

  Specifically, the UE in the beam on the primary communication path is already present in the beam on the primary communication path with the newly connected UE, that is, the target UE that transmits the SRS, and the secondary communication path is determined. May be classified as a UE that has been configured. In some cases, the secondary communication path corresponding to the target UE may be determined by detecting the SRS transmitted by the target UE using a narrow beam developed over the entire area.

  S305: Determine a secondary communication path corresponding to another UE in the beam on the primary communication path.

  Further, in some cases, after acquiring the primary communication path between the current BS and the target UE by determining, a secondary communication path corresponding to another UE sharing the primary communication path is further extracted, and the primary communication path The secondary communication path corresponding to all the UEs that communicate with each other, that is, all the UEs in the beam on the primary communication path may be determined. Another UE that shares the primary communication path is a UE that already exists in the beam on the primary communication path, and may record and store the secondary communication path between the existing UE and the current BS. Further, the recorded and stored secondary communication path may be extracted only to determine the existing secondary communication path of the UE.

  S306: Communicate with each UE according to the primary communication path and secondary communication path corresponding to each UE.

  In a specific embodiment, the frame formats of uplink and downlink subframes corresponding to UEs in the beam on the primary communication path correspond to UEs in the beam on the primary communication path and are obtained by determining. And then the communication path used to transmit the uplink and downlink subframes corresponding to each UE is determined, so that the BS in the beam on the primary communication path Communication with the UE is performed.

  By implementing this embodiment of the present invention, the primary communication path for communication between the current BS and the target UE that transmits the SRS can be determined according to the SRS signal, and each communication is performed using the primary communication path. The secondary communication path may be determined for the UE, and as a result, communication with each UE is performed based on the primary communication path and the secondary communication path, which can improve the data transmission throughput and data transmission efficiency of the system. Can be improved.

  Referring to FIG. 4, FIG. 4 is a schematic flowchart of a method for determining a secondary communication path according to an embodiment of the present invention. The method in this embodiment of the present invention is particularly applicable to communication equipment that can be used as a receiver, eg, BS or MS. Specifically, the method includes:

  S401: The sounding reference signal SRS transmitted in the target direction is received by the target transmitter using the narrow beam developed over the entire area.

  S402: Obtain channel quality in the target direction by calculation according to SRS.

  If the current BS receives an SRS transmitted UE, that is, an SRS transmitted using a narrow beam spread over the entire area by the target UE (target transmitter), the current BS calculates the channel quality in the current direction according to the SRS. .

  S403: It is determined whether the channel quality is higher than the channel quality corresponding to the previously determined secondary communication path.

  After obtaining the channel quality in the current direction by calculation, the current BS compares the channel quality in the current direction with the channel quality obtained by calculation at the previous time point, and the channel quality in the current direction is calculated at the previous time point. It is detected whether it is higher than the channel quality acquired by.

  S404: When the channel quality is higher than the channel quality corresponding to the previously determined secondary communication path, the communication path corresponding to the target direction is updated to the secondary communication path.

  If the channel quality in the target direction, that is, the current direction is higher than the channel quality obtained by calculation at the previous time point, it means that the communication path corresponding to the current direction is the secondary communication path between the current BS and the target UE. Indicates that it can be updated.

  Furthermore, before updating the communication path corresponding to the current direction to the secondary communication path between the current BS and the target UE, the channel quality in the current direction is higher than the channel quality obtained by calculation at the previous time point If detected, it may further be detected whether the communication path corresponding to the current direction is the primary communication path between the current BS and the target UE. When the communication path corresponding to the current direction is not the primary communication path, the communication path corresponding to the target direction is updated to the secondary communication path.

  In addition, when it is detected that the communication path corresponding to the current direction is not the primary communication path between the current BS and the target UE, the channel quality of the communication path corresponding to the current direction is more than the preset QoS threshold. May be further detected. When it is detected that the channel quality of the communication path corresponding to the current direction is higher than the QoS threshold, the communication path corresponding to the current direction may be updated to the secondary communication path. The QoS threshold may be set according to specific channel quality requirements, which is not limited in this embodiment of the invention.

  S405: The target transmitter receives the SRS transmitted in the corresponding direction obtained after the beam direction has changed using the narrow beam deployed across the entire area, and the target transmitter transmits the SRS transmitted in that direction in the target direction. Used as SRS.

  S406: When the detection with respect to the SRS transmitted in all directions using the narrow beam expanded by the target transmitter is completed, the secondary communication path of the target transmitter is determined.

  The target UE changes the beam direction according to a preset time interval, uses the corresponding direction acquired after the beam direction is changed as the target direction, and transmits the SRS in the target direction using a narrow beam developed over the entire area. . When the current BS receives the SRS transmitted by the target UE, the current BS performs S402 to S405 until the current BS completes the detection for the SRS transmitted in all directions using the narrow beam expanded by the target UE. Repeatedly execute and use the confirmed secondary communication path as the secondary communication path between the current BS and the target UE.

  By implementing this embodiment of the present invention, after receiving the SRS transmitted by the target UE, the current BS corresponds to the target UE by comparing the channel quality in the current direction with the channel quality in the direction of the previous time point. To determine whether or not to update the secondary communication path to be performed, and after the current BS completes the detection for the SRS transmitted by the target UE in a predetermined time interval in all directions using a narrow beam deployed throughout the entire secondary The communication path may be used as a secondary communication path between the current BS and the target UE.

  Referring to FIG. 5, FIG. 5 is a schematic flowchart of another method for determining a secondary communication path according to an embodiment of the present invention. Specifically, the method includes:

  S501: Receive a sounding reference signal SRS transmitted in all directions by using a narrow beam developed by the target transmitter throughout the entire area.

  S502: Calculate channel quality in all directions according to SRS.

  The target UE transmits an SRS in all directions using a narrow beam deployed across the entire area, and the current BS receives the SRS transmitted by the target UE and determines the channel quality of the communication path corresponding to the all directions according to the received SRS. calculate. Specifically, transmitting an SRS in all directions involves changing the beam direction according to a preset time interval, and using a narrow beam deployed across the entire area in the corresponding direction obtained after the beam direction changes. May be implemented by sending

  S503: The secondary communication path of the target transmitter is determined according to the channel quality that is omnidirectional and obtained by calculation.

  After acquiring the channel quality corresponding to all directions by calculation, the current BS sets the communication path corresponding to the direction having the optimum channel quality other than the channel quality in the direction of the primary communication path as the secondary communication path corresponding to the target UE. You may choose.

  Further, the channel quality corresponding to the communication path is set in advance before selecting the communication path corresponding to the direction having the optimum channel quality other than the channel quality in the direction of the primary communication path as the secondary communication path corresponding to the target UE. If it is further detected whether the channel quality is higher than the QoS threshold, and the channel quality corresponding to the communication path is higher than the QoS threshold, the communication path may be determined as a secondary communication path corresponding to the target UE.

  By implementing this embodiment of the present invention, after receiving the SRS transmitted in all directions using the narrow beam deployed by the UE in the whole area, the BS obtains the channel quality in all directions by calculation and comparison, The communication path corresponding to the direction having the optimum channel quality among the channel quality in all directions other than the channel quality in the direction of the primary communication path can be directly selected as the secondary communication path corresponding to the target UE.

  Further, communicating with the transmitter according to the primary communication path and the secondary communication path may include the following five communication scenarios.

Scenario 1: When there are at least two identifiers of a transmitter that communicates using a primary communication path, and the transmitter indicated by each identifier does not have a secondary communication path, uplink and downlink sub corresponding to the transmitter The number of frames is configured according to a preset configuration ratio, and the uplink and downlink subframes of the transmitter are transmitted in a time division multiplexing manner.

  The frame formats of the uplink and downlink subframes are the same, and the uplink and downlink subframes contain information corresponding to the transmitter, and the transmitter uses the frequency division multiplexing method to spread the bandwidth resources spread over the entire area. assign.

  Specifically, referring to FIG. 6, FIG. 6 is a schematic diagram of a communication scenario according to an embodiment of the present invention. In this scenario, there may be multiple transmitters that communicate using the primary communication path, i.e., there may be multiple transmitters in the beam corresponding to the primary communication path. In the specific example of FIG. 6, there are three UEs (that is, three transmitters) in the beam corresponding to the primary communication path, that is, UE1, UE2, and UE3, respectively. Does not have a route.

  Further, as shown in FIG. 7, FIG. 7 is a schematic diagram of resource allocation in the scenario of FIG. Specifically, UE1, UE2, and UE3 are distinguished by a frequency division scheme, and uplink and downlink are distinguished by a time division scheme.

  Furthermore, the uplink and downlink frame formats corresponding to each UE are the same. As shown in FIG. 8, FIG. 8 is a schematic diagram of the corresponding frame format in the scenario of FIG. The number of uplink and downlink subframes may be configured according to a preset configuration ratio (in FIG. 8, the configuration is performed at 4: 4), and the configuration ratio is according to the throughput of the uplink and downlink services. May be adjusted. Specifically, the SRS is inserted into uplink and downlink subframes according to a preset insertion interval. For example, one SRS signal may be inserted every two subframes, which is represented by a shaded block in FIG. The inserted SRS may be acquired by the current BS based on SRS information returned by UEs in the beam on the primary communication path. When inserting an SRS between downlink subframes or between a downlink subframe and an uplink subframe, it is necessary to wrap the SRS signal into a specific subframe S for insertion. When inserting an SRS between uplink subframes, the SRS need only be placed after the data block of the last subframe (or may be wrapped in a specific subframe S for insertion). As shown in FIG. 8, each uplink subframe U and each downlink subframe D sequentially includes information related to UE1, UE2, and UE3 according to frequency allocation, which are respectively U1 and D1, It can correspond to U2 and D2, and U3 and D3. Further, the SRS signal insertion interval may be adjusted according to the moving speed requirement.

  In scenario 1, there are multiple UEs in a beam (three UEs in scenario 1), and none of the UEs has a corresponding secondary communication path, In comparison, the beams of scenario 1 are narrowed to some extent, that is, the number of UEs covered by each beam is small. Therefore, when frequency bands are multiplexed in the frequency division scheme, a wider bandwidth can be allocated to each UE. For example, in a frequency band with a bandwidth of 300 MHz, the bandwidth is allocated equally to three UEs, each UE occupies a bandwidth of 100 MHz, and a bandwidth of 100 MHz is an uplink and downlink Can be supported by both. In a broadcast-type conventional cellular communication system, there are several hundred UEs in each beam, and the bandwidth of each UE is less than 1 MHz. Therefore, UE capacity and system capacity are improved.

Scenario 2: When there is one identifier of a transmitter that communicates using the primary communication path, and the transmitter indicated by the identifier does not have a secondary communication path, the uplink and downlink subframes corresponding to the transmitter The number is configured according to a preset configuration ratio, and the uplink and downlink subframes of the transmitter are transmitted in a time division multiplexing manner.

  The frame formats of the uplink and downlink subframes are the same, and the uplink and downlink subframes contain information related to the transmitter, and the transmitter occupies the bandwidth resources deployed throughout the entire area.

  Specifically, referring to FIG. 9, FIG. 9 is a schematic diagram of another communication scenario according to an embodiment of the present invention. As shown in FIG. 9, in this scenario, there is only one transmitter that communicates using the primary communication path, that is, there is only one UE in the beam corresponding to the primary communication path, that is, UE1, The UE does not have a secondary communication path. Scenario 2 may be considered a special example of scenario 1.

  Further, as shown in FIG. 10, FIG. 10 is a schematic diagram of resource allocation in the scenario of FIG. The UE 1 in the beam on the primary communication path exclusively occupies the one developed in the entire area, and is distinguished by the frequency division method, and the uplink and the downlink are distinguished by the time division method.

  Furthermore, the uplink and downlink frame formats corresponding to UE1 are the same. As shown in FIG. 11, FIG. 11 is a schematic diagram of a corresponding frame format in the scenario of FIG. Each uplink U1 and each downlink subframe D1 includes only information related to UE1. The number of uplink and downlink subframes may be configured according to a preset configuration ratio, eg, 4: 4, and the configuration ratio may be adjusted according to uplink and downlink service throughput. Specifically, the method of inserting the SRS signal in this scenario is the same as the method of inserting the SRS signal in the above-described scenario, and details are not described here. Further, the SRS signal insertion interval may be adjusted according to the moving speed requirement.

  In scenario 2, the UE does not have a corresponding secondary communication path, but there is only one UE in the beam and the UE uses bandwidth resources exclusively. For example, in a frequency band with a bandwidth of 300 MHz, the UE occupies a bandwidth of 300 MHz, and the 300 MHz bandwidth can be supported in both uplink and downlink, thus significantly increasing UE capacity and system capacity. It has been improved.

  Scenario 3: Assume that there are at least two identifiers of transmitters that communicate using the primary communication path, and that the transmitter indicated by each identifier has a secondary communication path.

  In any implementation, the primary communication path may be controlled to be used to transmit the transmitter downlink subframe indicated by the identifier, and the transmitter downlink subframe is a frequency division multiplexing scheme. Sent.

  The secondary communication path is controlled to be used to transmit the uplink subframe of the corresponding transmitter, and the uplink subframe of the transmitter is transmitted in a spatial multiplexing scheme, and the uplink subframe of the transmitter Exclusively occupies the bandwidth resources developed in the entire area, and the uplink subframe and the downlink subframe of the transmitter have different formats.

  Specifically, referring to FIG. 12, FIG. 12 is a schematic diagram of still another communication scenario according to an embodiment of the present invention. As shown in FIG. 12, in this scenario, there are a plurality of transmitters that perform communication using the primary communication path, that is, there are a plurality of transmitters in the beam corresponding to the primary communication path. In the specific example of FIG. 12, there are two UEs in the beam corresponding to the primary communication path, which are UE1 and UE2, respectively, and each of the two UEs has a secondary communication path that can be used.

  Further, as shown in FIG. 13, FIG. 13 is a schematic diagram of resource allocation in the scenario of FIG. Specifically, the uplinks of UE1 and UE2 in the beam on the primary communication path are distinguished by a space division scheme, and the downlinks of two UEs are distinguished by a frequency division scheme.

  Specifically, the primary communication path may be controlled to be used only for downlink subframe transmission, not for uplink subframe transmission, and accordingly, the secondary communication path may be used for downlink subframe transmission. Used only for uplink transmission, not transmission. The uplink and downlink frame formats of each UE are different and independent of each other. As shown in FIG. 14, FIG. 14 is a schematic diagram of a frame format in the scenario of FIG. The frame format in this scenario has no problem with the composition ratio of the number of uplink and downlink subframes. Specifically, each uplink subframe U includes only information related to UE1 or UE2, and the information corresponds to U1 or U2, respectively. Each downlink subframe D may sequentially include information on two UEs, namely D1 and D2. The method of inserting the SRS signal in this scenario is the same as the method of inserting the SRS signal in the above-described scenario, and details are not described here. Further, the SRS signal insertion interval may be adjusted according to the moving speed requirement.

  In scenario 3, there are multiple UEs in the beam, and each UE has an available secondary communication path. All UEs share downlink frequency band resources, and each UE exclusively uses uplink bandwidth resources. For example, in a frequency band with a bandwidth of 300 MHz, there are two UEs in the beam, the downlink of each UE occupies a bandwidth of 150 MHz, and the uplink of each UE occupies a bandwidth of 300 MHz To do. Thus, both UE capacity and system throughput capacity are significantly improved.

  In any implementation, the primary communication path may be controlled to be used for transmitting the uplink subframe of the transmitter indicated by the identifier, and the uplink subframe of the transmitter is a frequency division multiplexing scheme. Sent.

  The secondary communication path is controlled to be used to transmit the downlink subframe of the corresponding transmitter, and the downlink subframe of the transmitter is transmitted in a spatial multiplexing scheme, and the downlink subframe of the transmitter Exclusively occupies the bandwidth resources developed in the entire area, and the uplink subframe and the downlink subframe of the transmitter have different formats.

  Specifically, as shown in FIG. 15, FIG. 15 is a schematic diagram of another type of resource allocation in the scenario of FIG. The downlinks of UE1 and UE2 in the beam on the primary communication path are distinguished by a space division scheme, and the uplinks of two UEs are distinguished by a frequency division scheme.

  Specifically, the primary communication path may be controlled to be used only for uplink subframe transmission, and the secondary communication path may be used only for downlink transmission. The uplink and downlink frame formats of each UE are different and independent of each other. As shown in FIG. 16, FIG. 16 is a schematic diagram of another frame format in the scenario of FIG. Each downlink subframe D includes only information about UE1 or UE2, which corresponds to D1 or D2, respectively, and each uplink subframe U sequentially includes information about two UEs, namely U1 or U2. .

  In scenario 3, there are multiple UEs in the beam, and each UE has an available secondary communication path. All UEs share uplink frequency band resources, and each UE exclusively uses downlink bandwidth resources. For example, in a frequency band with a bandwidth of 300 MHz, there are two UEs in the beam, the uplink of each UE occupies a bandwidth of 150 MHz, and the downlink of each UE occupies a bandwidth of 300 MHz To do. Thus, both UE capacity and system throughput capacity are significantly improved.

  Scenario 4: When there is one identifier of a transmitter that communicates using the primary communication path and the transmitter indicated by the identifier has a corresponding secondary communication path, the uplink subframe and the downlink subframe of the transmitter The uplink subframe and the downlink subframe have different formats, and the transmitter occupies the bandwidth resources developed over the entire area.

  Specifically, referring to FIG. 17, FIG. 17 is a schematic diagram of still another communication scenario according to an embodiment of the present invention. As shown in FIG. 17, in this scenario, there is only one transmitter using the primary communication path, that is, there is only one UE in the beam corresponding to the primary communication path, that is, UE1, and the UE uses Has a possible secondary communication path.

  Further, as shown in FIG. 18, FIG. 18 is a schematic diagram of resource allocation in the scenario of FIG. Specifically, the UEs in the beam on the primary communication path may exclusively occupy those deployed in the entire area, and the uplink and the downlink are distinguished by the space division method.

  Specifically, the primary communication path may be controlled to be used only for downlink subframe transmission, and the secondary communication path may be used only for uplink transmission, or the primary communication path May be controlled to be used only for uplink subframe transmission and the secondary communication path may be used only for downlink transmission. The uplink and downlink frame formats are different and independent of each other. As shown in FIG. 19, FIG. 19 is a schematic diagram of a corresponding frame format in the scenario of FIG. The frame format has no problem with the composition ratio of the number of uplink and downlink subframes. Specifically, each uplink subframe U1 and each downlink subframe D1 includes only information on the UE. The method of inserting the SRS signal in this scenario is the same as the method of inserting the SRS signal in the above-described scenario, and details are not described here. Further, the SRS signal insertion interval may be adjusted according to the moving speed requirement.

  In scenario 4, there is only one UE in the beam, the UE has an available secondary communication path, and the UE uses bandwidth resources exclusively. For example, in a frequency band having a bandwidth of 300 MHz, the UE occupies a bandwidth of 300 MHz, and the 300 MHz bandwidth may be supported in both uplink and downlink. Therefore, the UE capacity is significantly improved.

  Scenario 5: There are at least two identifiers of a transmitter that communicates using a primary communication path, the number of secondary communication paths is greater than zero, and the number of secondary communication paths is less than the number of identifiers.

  Specifically, referring to FIG. 20, FIG. 20 is a schematic diagram of still another communication scenario according to an embodiment of the present invention. As shown in FIG. 20, in this scenario, there are a plurality of transmitters sharing the primary communication path, that is, there are a plurality of transmitters in the beam corresponding to the primary communication path. In the specific example of FIG. 20, two UEs, that is, UE1 and UE2, exist in the beam corresponding to the primary communication path, and only the UE1 has a secondary communication path that can be used.

  In any implementation, the primary communication path may be controlled to be used to transmit the transmitter downlink subframe, where the transmitter downlink subframe is transmitted in a frequency division multiplexing manner, The transmitter includes a first transmitter that does not have a secondary communication path, that is, UE2, and a second transmitter that has a secondary communication path, that is, UE1.

  The primary communication path is controlled to be used for transmitting the uplink subframe of the first transmitter, and the uplink subframe of the first transmitter is transmitted by frequency division multiplexing, The uplink and downlink subframes of the transmitters are transmitted by time division multiplexing.

  The secondary communication path is controlled to be used to transmit the uplink subframe of the second transmitter, the uplink subframe of the second transmitter is transmitted in a spatial multiplexing scheme, The format of the uplink subframe and the downlink subframe of the transmitter are different.

  Specifically, as shown in FIG. 21, FIG. 21 is a schematic diagram of resource allocation in the scenario of FIG. Specifically, the downlink of UE1 and UE2 in the beam on the primary communication path is distinguished by the frequency division scheme, the uplink and downlink of UE2 are distinguished by the time division scheme, and the uplink and downlink of UE1 The links are distinguished by a space division method.

  Specifically, the primary communication path may be controlled to be used only for downlink subframe transmission, and the secondary communication path may be used only for uplink subframe transmission. UE1 uplink and downlink frame formats are different and independent of each other, and UE2 uplink and downlink frame formats are the same. As shown in FIG. 22, FIG. 22 is a schematic diagram of a frame format in the scenario of FIG. Since UE1 and UE2 share the frame format of the downlink and downlink beam, when UE2 transmits uplink data in a time division multiplexing scheme, the bandwidth belonging to UE1 can only be in an idle state. The number of uplink and downlink subframes may be configured according to a preset configuration ratio, eg, 4: 4, and the configuration ratio may be adjusted according to the throughput of the uplink and downlink services. Since the uplink subframe U1 of UE1 can be transmitted by the spatial multiplexing method using the secondary communication path, the uplink subframe U1 of UE1 has an independent frame format. Specifically, each uplink subframe U1 transmitted using the secondary communication path includes only information related to UE1, and each downlink subframe D transmitted using the primary communication path includes information related to UE1 and Information on UE2 is sequentially included, that is, information on UE1 and information on UE2 correspond to D1 and D2, respectively. In each uplink subframe U, the frequency band belonging to UE1 is in an idle state and is represented by X in FIG. 22, and the frequency band belonging to UE2 includes information on UE2, that is, information on UE2 is U2 Corresponding to The method of inserting the SRS signal in this scenario is the same as the method of inserting the SRS signal in the above-described scenario, and details are not described here. The insertion interval of the SRS signal may be adjusted according to the moving speed requirement. Furthermore, the uplink data of UE2 may be further controlled to be transmitted in the uplink subframe and in the bandwidth of UE1 in the primary communication path using a specific technique.

  In scenario 5, there are multiple UEs in the beam, but each UE does not have an available secondary communication path. All UEs share downlink frequency band resources, and UEs having sub-optimal paths exclusively use uplink bandwidth resources. For example, in a frequency band having a bandwidth of 300 MHz, when the beam includes only UE1 and UE2, and only UE1 has a corresponding secondary communication path, the downlink of each UE occupies a bandwidth of 150 MHz, The uplink of UE2 occupies a bandwidth of 150 MHz, and the uplink of UE1 occupies a bandwidth of 300 MHz. Thus, both UE capacity and system throughput capacity are significantly improved.

  In any implementation, the primary communication path may be controlled to be used to transmit a transmitter uplink subframe, where the transmitter uplink subframe is transmitted in a frequency division multiplexing manner, The transmitter includes a first transmitter that does not have a secondary communication path, that is, UE2, and a second transmitter that has a secondary communication path, that is, UE1.

  The primary communication path is controlled to be used to transmit the downlink subframe of the first transmitter, and the downlink subframe of the first transmitter is transmitted by frequency division multiplexing, The uplink and downlink subframes of the transmitters are transmitted by time division multiplexing.

  The secondary communication path is controlled to be used to transmit the downlink subframe of the second transmitter, and the downlink subframe of the second transmitter is transmitted in a spatial multiplexing scheme, The format of the uplink subframe and the downlink subframe of the transmitter are different.

  Specifically, referring to FIG. 23, FIG. 23 is a schematic diagram of another type of resource allocation in the scenario shown in FIG. The uplinks of UE1 and UE2 in the beam on the primary communication path are distinguished by frequency division, the uplink and downlink of UE2 are distinguished by time division, and the uplink and downlink of UE1 are spatially divided. Differentiated by method.

  Specifically, the primary communication path may be controlled to be used only for uplink subframe transmission, and the secondary communication path may be used only for downlink subframe transmission. UE1 uplink and downlink frame formats are different and independent of each other, and UE2 uplink and downlink frame formats are the same. As shown in FIG. 24, FIG. 24 is a schematic diagram of another frame format in the scenario of FIG. Since UE1 and UE2 share the frame format of the uplink and the uplink beam, when UE2 transmits downlink data by the time division multiplexing method, the bandwidth belonging to UE1 can be only in the idle state. The number of uplink and downlink subframes may be configured according to a preset configuration ratio, eg, 4: 4, and the configuration ratio may be adjusted according to the throughput of the uplink and downlink services. Since the downlink subframe U1 of UE1 can be transmitted in the spatial multiplexing scheme using the secondary communication path, the downlink subframe D1 of UE1 has an independent frame format. Specifically, each downlink subframe D1 transmitted using the secondary communication path includes only information related to UE1, and each uplink subframe U transmitted using the primary communication path includes information related to UE1 and Information on UE2 is sequentially included, that is, information on UE1 and information on UE2 correspond to U1 and U2, respectively. In each downlink subframe D, the frequency band belonging to UE1, that is, X in FIG. 24 is in an idle state, and the frequency band belonging to UE2 includes information on UE2, that is, information on UE2 corresponds to D2. To do. Furthermore, the downlink data of UE2 may be further controlled to be transmitted in the downlink subframe and in the bandwidth of UE1 in the primary communication path using a specific technique.

  In the above scenario, there are multiple UEs in the beam, but each UE does not have an available secondary communication path. All UEs share uplink frequency band resources, and UEs having sub-optimal paths exclusively use downlink bandwidth resources. For example, in a frequency band having a bandwidth of 300 MHz, if the beam includes only UE1 and UE2, and only UE1 has a corresponding secondary communication path, the uplink of each UE occupies a bandwidth of 150 MHz, The downlink of UE2 occupies a bandwidth of 150 MHz, and the downlink of UE1 occupies a bandwidth of 300 MHz. Thus, both UE capacity and system throughput capacity are significantly improved.

  The frame format is determined according to a specific communication scenario, and the communication path (including the primary communication path and the corresponding secondary communication path) used for transmitting uplink and downlink subframes is determined for each UE. After that, it is possible to prepare for communication between the BS and the UE.

  After determining the primary communication path for communication with the UE that transmits the SRS according to the received SRS by implementing this embodiment of the present invention, the current BS further determines the secondary communication path for the UE, Extract the secondary communication path of another UE in the beam on the primary communication path, and communicate with each UE in the beam on the primary communication path based on the communication scenario established according to the primary communication path and the secondary communication path As a result, the data transmission throughput and data transmission efficiency of the system can be effectively improved.

  The present invention relates to the field of communication technology, and in particular, to a communication method and a communication apparatus.

Features a coverage area. The same sector can be thought of as one beam, and the MSs covered by that beam share bandwidth by occupying different frequencies, the more MS covered by that beam, the more bandwidth each MS occupies And the capacity of each MS is reduced, and the size of service data transmitted by the user is greatly limited.

  With the development of network technology, it is certain that human society will face the next wave of digital society. For example, 5G wireless networks need to meet the requirement of larger and faster capacity increase, which requires more new frequency band allocations.

High-frequency wireless communication is already an inevitable flow for future wireless communication development.

  DESCRIPTION OF EMBODIMENTS The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Of course, the described embodiments are merely some of the embodiments of the present invention, not all. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

  The receiver in the embodiment of the present invention may refer to a base station (full name in English: Base Station, abbreviated as BS) or a mobile station (full name in English: Mobile Station, abbreviated as MS). The transmitter may also be an MS or a BS, and communications in the embodiments of the present invention include, but are not limited to, communications between BSs, between BSs and MSs, and between MSs. . The MS includes user equipment (complete name in English: User Equipment, abbreviated UE).

  Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a communication device according to an embodiment of the present invention. The apparatus in this embodiment of the present invention is particularly applicable to a communication device that can be used as a receiver, for example, a base station. Specifically, the apparatus may include a first confirmation module 10, a second confirmation module 20, and a communication module 30.

  The first determination module 10 is configured to determine a primary communication path to the target transmitter according to the first SRS when the first sounding reference signal SRS is received, and the target transmitter is configured to It is a transmitter which transmits.

  In a specific embodiment, a transmitter, eg, a UE, can be connected using a wide angle beam to ensure normal communication. The connection process using the wide-angle beam is the same as the connection process using the conventional wireless cellular communication, and details are not described here. Specifically, a sounding reference signal (sounding reference signal, abbreviated as SRS) transmitted by a target transmitter, for example, a newly connected UE, using a wide-angle beam spread over the entire area, that is, the first If an SRS is received, the first determination module 10 may be activated to determine the primary communication path between the UE and the current receiver or BS.

  The primary communication path can also refer to a communication path used during connection by conventional wireless cellular communication, that is, a communication path having an optimum channel quality. Generally, the primary communication path is a prospect (full name in English: Line of Sight, abbreviated LoS) channel. If there is no LoS channel, or in some very special cases, the quality of the LoS channel is inferior to the quality of the non-line-of-sight (non-Line of Sight, abbreviated NLoS) channel, the primary communication path is NLoS channel.

  In some cases, the method in this embodiment of the present invention can be implemented by using the millimeter wave band as a communication frequency band. Millimeter wave refers to a high frequency band from 30 GHz to 300 GHz and has a relatively strong directivity as well as a narrower focused beam. Therefore, higher antenna gain can be obtained by performing communication using millimeter waves. In addition, since millimeter waves are characterized by focused beam energy, energy losses on the reflection and diffraction paths are relatively small. Therefore, millimeter waves can be used for communication.

  The second determination module 20 acquires the identifier of the transmitter that performs communication using the primary communication path determined by the first determination module 10, and determines the secondary communication path of the transmitter indicated by each identifier. Composed.

  After the first determination module 10 determines the primary communication path corresponding to the target UE, the second determination module 20 determines the identifier corresponding to the UE in the beam on the primary communication path between the UE and the current BS. Acquisition, that is, an identifier of a UE that performs communication using a primary communication path may be acquired, and a secondary communication path, that is, a communication path having an optimum channel quality other than the primary communication path may be determined for each UE.

  In a specific embodiment, after connecting the target UE by conventional wireless cellular communication, the BS corresponding to the target UE, i.e. the current receiver, splits the wide angle beam into narrow beams and thus the user is split. In order to control and improve user capacity and system capacity, the respective areas for the secondary communication path corresponding to the UE may be further searched. Specifically, the secondary communication path may be an NLoS channel in a general case.

  The communication module 30 is configured to communicate with the transmitter according to the primary communication path determined by the first determination module 10 and the secondary communication path determined by the second determination module 20.

  In a specific embodiment, the communication module 30 may communicate with UEs in the beam on the primary communication path according to the established primary communication path and secondary communication path corresponding to the UE in the beam on the primary communication path.

By implementing the present embodiment of the present invention, the primary communication path for communication between the SR S received by the receiver thus current transmitter and the target transmitter is confirmed, the communication with the primary communication path The secondary communication path is determined for each transmitter that performs communication, and as a result, communication with each transmitter is performed based on the primary communication path and the secondary communication path, thereby effectively reducing the transmission capacity of the system. Can improve.

  Referring to FIG. 2, FIG. 2 is a schematic structural diagram of another communication apparatus according to an embodiment of the present invention. The apparatus in the present embodiment of the present invention includes the first determination module 10, the second determination module 20, and the communication module 30 of the communication device. Furthermore, in this embodiment of the invention, the first determination module 10 specifically includes a direction determination unit 101 and a narrow beam narrowing unit 102.

  The direction determination unit 101 is configured to determine an optimal arrival direction according to a predetermined determination rule when the first SRS is received.

  The first SRS is transmitted by a target transmitter, for example, a newly connected UE, using a wide-angle beam that is spread over the entire area.

Direction determination unit 101, SR S target UE is transmitted using a wide-angle beam expanded into the entire region, i.e., when receiving the first SRS, the direction determining unit 101, from a direction just received the SR S, preset According to the determined rule, the optimal arrival direction can be determined, and position information regarding the optimal arrival direction can be returned to the newly connected UE. The preset decision rules may be formed according to a specific algorithm and specific criteria. For example, the direction determining unit 101, therefore in all directions of the SR S, all directions to a corresponding signal-to-interference-and-noise power ratio (English with full name: Signal to Interference plus Noise Ratio, abbreviated SINR) Gets the value, SINR The direction corresponding to the maximum SINR value among the values may be selected as the optimum arrival direction.

  The narrow beam unit 102 is configured to narrow the wide-angle beam used by the target transmitter in the optimum arrival direction determined by the direction determination unit 101, and to determine the communication path on which the narrow beam is placed as the primary communication path. The

After the direction determination unit 101 determines the optimum arrival direction, the narrow beam narrowing unit 102 can narrow the wide-angle beam used by the UE in the optimum arrival direction. For example, narrow beam of unit 102 controls the relevant beam control module such Purikodin grayed adjustment module and beamforming spider Joules, narrowing in the optimal direction of arrival of the beam. Furthermore, in relation to the optimal direction of arrival, and after receiving the information that BS returns, UE that has transmitted the SR S, or target UE, the relevant beam configuration such Purikodin grayed adjustment module and beamforming spider Joules In order to control the module and obtain a primary communication path between the current BS and the target UE, the beam can be narrowed in the optimal direction of arrival.

Furthermore, in this embodiment of the invention, the second confirmation module 20 is
Configured to acquire the identifier of the transmitter that performs communication using the primary communication path and to determine the secondary communication path of the target transmitter according to the second SRS transmitted by the target transmitter corresponding to the target identifier in the identifier The first route acquisition unit 201, the target identifier is the identifier of the target transmitter, the first route acquisition unit 201,
A second path acquisition unit 202 configured to determine a secondary communication path of a transmitter indicated by another identifier in the identifier;
Can be included.

  The second SRS is an SRS transmitted by a transmitter using a narrow beam spread over the entire area.

  After acquiring the primary communication path between the current BS and the target UE by confirming, the first path acquisition unit 201 may acquire the secondary communication path of the target UE, and the second path acquisition unit 202 The secondary communication path corresponding to another UE sharing the primary communication path is extracted, and all UEs performing communication using the primary communication path, that is, all UEs in the beam on the primary communication path are supported. A secondary communication path may be determined. Another UE that shares the primary communication path is a UE that already exists in the beam on the primary communication path, and may record and store the secondary communication path between the existing UE and the current BS. Furthermore, when determining the secondary communication path of the existing UE, the second path acquisition unit 202 only needs to extract the recorded and stored secondary communication path.

  Further, in some cases, the first route acquisition unit 201 may include a determination subunit 2011 and an update subunit 2012.

  The decision subunit 2011 receives the second SRS transmitted in the target direction using the narrow beam deployed by the target transmitter in the entire area, and obtains the channel quality in the target direction by calculation according to the second SRS. And configured to determine whether the channel quality is higher than the channel quality corresponding to the previously established secondary communication path.

  When the decision subunit 2011 receives the SRS transmitted using the narrow beam that the target UE has deployed over the entire area, that is, the second SRS, the decision subunit 2011 calculates the channel quality in the current direction according to the SRS, and calculates After obtaining the channel quality in the current direction by comparing the channel quality in the current direction with the channel quality obtained by calculation at the previous time point, the channel quality in the current direction is obtained by calculation at the previous time point. May be detected.

  The update subunit 2012 determines that the determination result of the determination subunit 2011 is that the channel quality is higher than the channel quality corresponding to the previously determined secondary communication path, the secondary communication path corresponding to the target direction is secondary It is configured to update to the communication path.

Update subunit 2012
If the determination result of the determination subunit 2011 is that the channel quality is higher than the channel quality corresponding to the previously determined secondary communication path, whether the communication path corresponding to the target direction is the primary communication path If the communication path corresponding to the target direction is not the primary communication path, the channel quality of the communication path corresponding to the target direction is higher than the preset communication service quality QoS threshold. If the channel quality of the communication path corresponding to the target direction is higher than the QoS threshold, the communication path corresponding to the target direction may be specifically configured to be updated to the secondary communication path.

  If the decision subunit 2011 detects that the channel quality in the target direction, i.e., the current direction is higher than the channel quality obtained by calculation at the previous time, it means that the communication path corresponding to the current direction is the current BS. It shows that it can update to the secondary communication path | route between target UEs.

  Furthermore, before updating the communication path corresponding to the current direction to the secondary communication path between the current BS and the target UE, the channel quality in the current direction is higher than the channel quality obtained by calculation at the previous time point If detected, it may further be detected whether the communication path corresponding to the current direction is the primary communication path between the current BS and the target UE. When the communication path corresponding to the current direction is not the primary communication path, the communication path corresponding to the target direction is updated to the secondary communication path.

  Furthermore, when it is detected that the communication path corresponding to the current direction is not the primary communication path between the current BS and the target UE, the channel quality of the communication path corresponding to the current direction is set to a predetermined service quality ( Whether it is higher than a threshold in English (full name: Quality of Service, abbreviated QoS) may be further detected. When it is detected that the channel quality of the communication path corresponding to the current direction is higher than the QoS threshold, the communication path corresponding to the current direction may be updated to the secondary communication path. The QoS threshold may be set according to specific channel quality requirements, which is not limited in this embodiment of the invention.

  Specifically, the target UE changes the beam direction according to a preset time interval, uses the corresponding direction acquired after the beam direction has changed as the target direction, and uses the narrow beam deployed throughout the target direction. Send SRS to The decision subunit 2011 receives the SRS transmitted by the target UE in the target direction, and calculates the channel quality in that direction until the first route acquisition unit 201 completes the detection of the SRS transmitted by the target UE in all directions. And the determined secondary communication path is used as the secondary communication path between the current BS and the target UE.

  In addition, in some cases, determining the secondary communication path corresponding to the target UE can be achieved by calculating and comparing in all directions after the BS receives the SRS transmitted in all directions using the narrow beam deployed by the UE. Channel quality is acquired, and the communication path corresponding to the direction with the optimal channel quality (meeting a preset QoS threshold) out of the channel quality in all directions other than the channel quality in the direction of the primary communication path corresponds to the target UE The secondary communication path to be selected may be selected directly.

Insertion module 40 configured to insert a third SRS in uplink and downlink subframes according to a preset insertion interval
May further be included.

Insert module is
Insert the third SRS directly in the uplink subframe or wrap the third SRS in a specific subframe and then insert the specific subframe in the uplink subframe In particular, it is configured to insert a specific subframe within the downlink subframe after wrapping the third SRS, or at a place where the downlink subframe and the uplink subframe are switched.

  The third SRS is obtained by the current BS (ie, the receiver) according to the SRS information returned by the corresponding UE.

  In a specific embodiment, the frame format is determined according to a secondary communication path corresponding to a UE in the beam on the primary communication path, and then a communication path for transmitting uplink and downlink subframes is determined, As a result, communication between the BS and the UE in the beam on the primary communication path is performed.

  After determining the primary communication path for communication with the UE that transmits the SRS according to the received SRS by implementing this embodiment of the present invention, the current BS further determines the secondary communication path for the UE, Extract the secondary communication path of another UE in the beam on the primary communication path, and communicate with each UE in the beam on the primary communication path based on the communication scenario established according to the primary communication path and the secondary communication path As a result, the data transmission throughput and data transmission efficiency of the system can be effectively improved.

  Referring to FIG. 3, FIG. 3 is a schematic interaction diagram of a communication method according to an embodiment of the present invention. This embodiment of the present invention will be described using communication between a BS (ie, a receiver) and a UE (ie, a transmitter) as an example. Specifically, the method includes:

  S301: The target UE transmits an SRS using a wide-angle beam spread over the entire area.

  S302: The BS determines the primary communication path according to the SRS.

  In a specific embodiment, the UE may be connected using a wide angle beam to ensure normal communication. The connection process using the wide-angle beam is the same as the connection process using the conventional wireless cellular communication. Specifically, when the target UE, for example, a newly connected UE receives an SRS transmitted using a wide-angle beam spread over the entire area, the current BS is started and primary communication between the current BS and the UE The route can be determined.

  In any implementation scheme, when the primary communication path between the BS and the target UE is determined in this embodiment of the present invention, an optimal arrival direction is determined according to the received SRS to determine the primary communication path. Can be done. The SRS is transmitted by a target UE, for example, a newly connected UE, using a wide-angle beam spread over the entire area.

Specifically, the current BS is, when receiving the SR S target UE is transmitted using a wide-angle beam expanded into the entire region, the current BS is from a direction just received the SR S, according to established rules set in advance, The optimum arrival direction can be determined, and the position information related to the optimum arrival direction can be returned to the newly connected UE. The preset decision rules may be formed according to a specific algorithm and specific criteria. For example, BS is therefore in all directions of the SR S, obtains the SINR value corresponding to the omnidirectional may select the maximum direction corresponding to the SINR value of the SINR value as an optimum direction of arrival.

After the optimum arrival direction is determined, the BS and the UE can narrow the wide-angle beam used by the UE in the optimum arrival direction. For example, the BS and the UE, by controlling the relevant beam control module such Purikodin grayed adjustment module and beamforming spider Joules, narrowing in the optimal direction of arrival of the beam, narrow beam is present BS and the target UE The communication route arranged as the primary communication route between the two is determined.

  S303: The target UE schedules another sub-array and transmits an SRS using a narrow beam spread over the entire area.

  S304: The BS determines a secondary communication path that can be used by the target UE according to the SRS.

  After determining the primary communication path of the target UE, in order to determine the secondary communication path of the UE indicated by each identifier, that is, the communication path having the optimum channel quality other than the primary communication path, between the target UE and the current BS The identifier of the UE that performs communication using the primary communication path, that is, the identifier corresponding to each UE in the beam on the primary communication path may be acquired.

In a specific embodiment, after connecting the target UE by conventional wireless cellular communication, the BS corresponding to the target UE, i.e. the current receiver , also splits the user so that the wide-angle beam is split into narrow beams. In order to control and improve user capacity and system capacity, the corresponding area for the secondary communication path corresponding to the UE may be further searched. Specifically, the secondary communication path may be an NLoS channel in a general case.

  Specifically, the UE in the beam on the primary communication path is already present in the beam on the primary communication path with the newly connected UE, that is, the target UE that transmits the SRS, and the secondary communication path is determined. May be classified as a UE that has been configured. In some cases, the secondary communication path corresponding to the target UE may be determined by detecting the SRS transmitted by the target UE using a narrow beam developed over the entire area.

  S305: Determine a secondary communication path corresponding to another UE in the beam on the primary communication path.

  Further, in some cases, after acquiring the primary communication path between the current BS and the target UE by determining, a secondary communication path corresponding to another UE sharing the primary communication path is further extracted, and the primary communication path The secondary communication path corresponding to all the UEs that communicate with each other, that is, all the UEs in the beam on the primary communication path may be determined. Another UE that shares the primary communication path is a UE that already exists in the beam on the primary communication path, and may record and store the secondary communication path between the existing UE and the current BS. Further, the recorded and stored secondary communication path may be extracted only to determine the existing secondary communication path of the UE.

  S306: Communicate with each UE according to the primary communication path and secondary communication path corresponding to each UE.

  In a specific embodiment, the frame formats of uplink and downlink subframes corresponding to UEs in the beam on the primary communication path correspond to UEs in the beam on the primary communication path and are obtained by determining. And then the communication path used to transmit the uplink and downlink subframes corresponding to each UE is determined, so that the BS in the beam on the primary communication path Communication with the UE is performed.

By implementing this embodiment of the present invention, the primary communication path for communication between the target UE to send the current BS and SRS, therefore possible to determine the SR S, performs communication using the primary communication path A secondary communication path may be determined for each UE, and as a result, communication with each UE is performed based on the primary communication path and the secondary communication path, which increases the data transmission throughput and data transmission efficiency of the system. It can be effectively improved.

  Referring to FIG. 4, FIG. 4 is a schematic flowchart of a method for determining a secondary communication path according to an embodiment of the present invention. The method in this embodiment of the present invention is particularly applicable to communication equipment that can be used as a receiver, eg, BS or MS. Specifically, the method includes:

  S401: The sounding reference signal SRS transmitted in the target direction is received by the target transmitter using the narrow beam developed over the entire area.

  S402: Obtain channel quality in the target direction by calculation according to SRS.

  If the current BS receives an SRS transmitted UE, that is, an SRS transmitted using a narrow beam spread over the entire area by the target UE (target transmitter), the current BS calculates the channel quality in the current direction according to the SRS. .

  S403: It is determined whether the channel quality is higher than the channel quality corresponding to the previously determined secondary communication path.

  After obtaining the channel quality in the current direction by calculation, the current BS compares the channel quality in the current direction with the channel quality obtained by calculation at the previous time point, and the channel quality in the current direction is calculated at the previous time point. It is detected whether it is higher than the channel quality acquired by.

  S404: When the channel quality is higher than the channel quality corresponding to the previously determined secondary communication path, the communication path corresponding to the target direction is updated to the secondary communication path.

  If the channel quality in the target direction, that is, the current direction is higher than the channel quality obtained by calculation at the previous time point, it means that the communication path corresponding to the current direction is the secondary communication path between the current BS and the target UE. Indicates that it can be updated.

  Furthermore, before updating the communication path corresponding to the current direction to the secondary communication path between the current BS and the target UE, the channel quality in the current direction is higher than the channel quality obtained by calculation at the previous time point If detected, it may further be detected whether the communication path corresponding to the current direction is the primary communication path between the current BS and the target UE. When the communication path corresponding to the current direction is not the primary communication path, the communication path corresponding to the target direction is updated to the secondary communication path.

  In addition, when it is detected that the communication path corresponding to the current direction is not the primary communication path between the current BS and the target UE, the channel quality of the communication path corresponding to the current direction is more than the preset QoS threshold. May be further detected. When it is detected that the channel quality of the communication path corresponding to the current direction is higher than the QoS threshold, the communication path corresponding to the current direction may be updated to the secondary communication path. The QoS threshold may be set according to specific channel quality requirements, which is not limited in this embodiment of the invention.

  S405: The target transmitter receives the SRS transmitted in the corresponding direction obtained after the beam direction has changed using the narrow beam deployed across the entire area, and the target transmitter transmits the SRS transmitted in that direction in the target direction. Used as SRS.

  S406: When the detection with respect to the SRS transmitted in all directions using the narrow beam expanded by the target transmitter is completed, the secondary communication path of the target transmitter is determined.

  The target UE changes the beam direction according to a preset time interval, uses the corresponding direction acquired after the beam direction is changed as the target direction, and transmits the SRS in the target direction using a narrow beam developed over the entire area. . When the current BS receives the SRS transmitted by the target UE, the current BS performs S402 to S405 until the current BS completes the detection for the SRS transmitted in all directions using the narrow beam expanded by the target UE. Repeatedly execute and use the confirmed secondary communication path as the secondary communication path between the current BS and the target UE.

  By implementing this embodiment of the present invention, after receiving the SRS transmitted by the target UE, the current BS corresponds to the target UE by comparing the channel quality in the current direction with the channel quality in the direction of the previous time point. To determine whether or not to update the secondary communication path to be performed, and after the current BS completes the detection for the SRS transmitted by the target UE in a predetermined time interval in all directions using a narrow beam deployed throughout the entire secondary The communication path may be used as a secondary communication path between the current BS and the target UE.

  Referring to FIG. 5, FIG. 5 is a schematic flowchart of another method for determining a secondary communication path according to an embodiment of the present invention. Specifically, the method includes:

  S501: Receive a sounding reference signal SRS transmitted in all directions by using a narrow beam developed by the target transmitter throughout the entire area.

  S502: Calculate channel quality in all directions according to SRS.

  The target UE transmits an SRS in all directions using a narrow beam deployed across the entire area, and the current BS receives the SRS transmitted by the target UE and determines the channel quality of the communication path corresponding to the all directions according to the received SRS. calculate. Specifically, transmitting an SRS in all directions involves changing the beam direction according to a preset time interval, and using a narrow beam deployed across the entire area in the corresponding direction obtained after the beam direction changes. May be implemented by sending

  S503: The secondary communication path of the target transmitter is determined according to the channel quality that is omnidirectional and obtained by calculation.

  After acquiring the channel quality corresponding to all directions by calculation, the current BS sets the communication path corresponding to the direction having the optimum channel quality other than the channel quality in the direction of the primary communication path as the secondary communication path corresponding to the target UE. You may choose.

  Further, the channel quality corresponding to the communication path is set in advance before selecting the communication path corresponding to the direction having the optimum channel quality other than the channel quality in the direction of the primary communication path as the secondary communication path corresponding to the target UE. If it is further detected whether the channel quality is higher than the QoS threshold, and the channel quality corresponding to the communication path is higher than the QoS threshold, the communication path may be determined as a secondary communication path corresponding to the target UE.

  By implementing this embodiment of the present invention, after receiving the SRS transmitted in all directions using the narrow beam deployed by the UE in the whole area, the BS obtains the channel quality in all directions by calculation and comparison, The communication path corresponding to the direction having the optimum channel quality among the channel quality in all directions other than the channel quality in the direction of the primary communication path can be directly selected as the secondary communication path corresponding to the target UE.

  Further, communicating with the transmitter according to the primary communication path and the secondary communication path may include the following five communication scenarios.

Scenario 1: When there are at least two identifiers of a transmitter that communicates using a primary communication path, and the transmitter indicated by each identifier does not have a secondary communication path, uplink and downlink sub corresponding to the transmitter The number of frames is configured according to a preset configuration ratio, and the uplink and downlink subframes of the transmitter are transmitted in a time division multiplexing manner.

  The frame formats of the uplink and downlink subframes are the same, and the uplink and downlink subframes contain information corresponding to the transmitter, and the transmitter uses the frequency division multiplexing method to spread the bandwidth resources spread over the entire area. assign.

  Specifically, referring to FIG. 6, FIG. 6 is a schematic diagram of a communication scenario according to an embodiment of the present invention. In this scenario, there may be multiple transmitters that communicate using the primary communication path, i.e., there may be multiple transmitters in the beam corresponding to the primary communication path. In the specific example of FIG. 6, there are three UEs (that is, three transmitters) in the beam corresponding to the primary communication path, that is, UE1, UE2, and UE3, respectively. Does not have a route.

  Further, as shown in FIG. 7, FIG. 7 is a schematic diagram of resource allocation in the scenario of FIG. Specifically, UE1, UE2, and UE3 are distinguished by a frequency division scheme, and uplink and downlink are distinguished by a time division scheme.

Furthermore, the uplink and downlink frame formats corresponding to each UE are the same. As shown in FIG. 8, FIG. 8 is a schematic diagram of the corresponding frame format in the scenario of FIG. The number of uplink and downlink subframes may be configured according to a preset configuration ratio (in FIG. 8, the configuration is performed at 4: 4), and the configuration ratio is according to the throughput of the uplink and downlink services. May be adjusted. Specifically, the SRS is inserted into uplink and downlink subframes according to a preset insertion interval. For example, one SRS may be inserted every two subframes, which is represented by a shaded block in FIG. The inserted SRS may be acquired by the current BS based on SRS information returned by UEs in the beam on the primary communication path. When inserting the SRS between the downlink inter-subframe or a downlink subframe and the uplink subframe, the SR S, for insertion, it is necessary to wrap the particular subframe S. When inserting an SRS between uplink subframes, the SRS need only be placed after the data block of the last subframe (or may be wrapped in a specific subframe S for insertion). As shown in FIG. 8, each uplink subframe U and each downlink subframe D sequentially includes information related to UE1, UE2, and UE3 according to frequency allocation, which are respectively U1 and D1, It can correspond to U2 and D2, and U3 and D3. Further, the insertion interval of the SRS may be adjusted according to the moving speed requirement.

  In scenario 1, there are multiple UEs in a beam (three UEs in scenario 1), and none of the UEs has a corresponding secondary communication path, In comparison, the beams of scenario 1 are narrowed to some extent, that is, the number of UEs covered by each beam is small. Therefore, when frequency bands are multiplexed in the frequency division scheme, a wider bandwidth can be allocated to each UE. For example, in a frequency band with a bandwidth of 300 MHz, the bandwidth is allocated equally to three UEs, each UE occupies a bandwidth of 100 MHz, and a bandwidth of 100 MHz is an uplink and downlink Can be supported by both. In a broadcast-type conventional cellular communication system, there are several hundred UEs in each beam, and the bandwidth of each UE is less than 1 MHz. Therefore, UE capacity and system capacity are improved.

Scenario 2: When there is one identifier of a transmitter that communicates using the primary communication path, and the transmitter indicated by the identifier does not have a secondary communication path, the uplink and downlink subframes corresponding to the transmitter The number is configured according to a preset configuration ratio, and the uplink and downlink subframes of the transmitter are transmitted in a time division multiplexing manner.

  The frame formats of the uplink and downlink subframes are the same, and the uplink and downlink subframes contain information related to the transmitter, and the transmitter occupies the bandwidth resources deployed throughout the entire area.

  Specifically, referring to FIG. 9, FIG. 9 is a schematic diagram of another communication scenario according to an embodiment of the present invention. As shown in FIG. 9, in this scenario, there is only one transmitter that communicates using the primary communication path, that is, there is only one UE in the beam corresponding to the primary communication path, that is, UE1, The UE does not have a secondary communication path. Scenario 2 may be considered a special example of scenario 1.

  Further, as shown in FIG. 10, FIG. 10 is a schematic diagram of resource allocation in the scenario of FIG. The UE 1 in the beam on the primary communication path exclusively occupies the one developed in the entire area, and is distinguished by the frequency division method, and the uplink and the downlink are distinguished by the time division method.

Furthermore, the uplink and downlink frame formats corresponding to UE1 are the same. As shown in FIG. 11, FIG. 11 is a schematic diagram of a corresponding frame format in the scenario of FIG. Each uplink subframe U1 and each downlink subframe D1 include only information related to UE1. The number of uplink and downlink subframes may be configured according to a preset configuration ratio, eg, 4: 4, and the configuration ratio may be adjusted according to uplink and downlink service throughput. Specifically, the method for inserting SRS in this scenario is the same as the method for inserting SRS in the above-described scenario, and details are not described here. Further, the insertion interval of the SRS may be adjusted according to the moving speed requirement.

  In scenario 2, the UE does not have a corresponding secondary communication path, but there is only one UE in the beam and the UE uses bandwidth resources exclusively. For example, in a frequency band with a bandwidth of 300 MHz, the UE occupies a bandwidth of 300 MHz, and the 300 MHz bandwidth can be supported in both uplink and downlink, thus significantly increasing UE capacity and system capacity. It has been improved.

  Scenario 3: Assume that there are at least two identifiers of transmitters that communicate using the primary communication path, and that the transmitter indicated by each identifier has a secondary communication path.

  In any implementation, the primary communication path may be controlled to be used to transmit the transmitter downlink subframe indicated by the identifier, and the transmitter downlink subframe is a frequency division multiplexing scheme. Sent.

  The secondary communication path is controlled to be used to transmit the uplink subframe of the corresponding transmitter, and the uplink subframe of the transmitter is transmitted in a spatial multiplexing scheme, and the uplink subframe of the transmitter Exclusively occupies the bandwidth resources developed in the entire area, and the uplink subframe and the downlink subframe of the transmitter have different formats.

  Specifically, referring to FIG. 12, FIG. 12 is a schematic diagram of still another communication scenario according to an embodiment of the present invention. As shown in FIG. 12, in this scenario, there are a plurality of transmitters that perform communication using the primary communication path, that is, there are a plurality of transmitters in the beam corresponding to the primary communication path. In the specific example of FIG. 12, there are two UEs in the beam corresponding to the primary communication path, which are UE1 and UE2, respectively, and each of the two UEs has a secondary communication path that can be used.

  Further, as shown in FIG. 13, FIG. 13 is a schematic diagram of resource allocation in the scenario of FIG. Specifically, the uplinks of UE1 and UE2 in the beam on the primary communication path are distinguished by a space division scheme, and the downlinks of two UEs are distinguished by a frequency division scheme.

Specifically, the primary communication path may be controlled to be used only for downlink subframe transmission, not for uplink subframe transmission, and accordingly, the secondary communication path may be used for downlink subframe transmission. Used only for uplink transmission, not transmission. The uplink and downlink frame formats of each UE are different and independent of each other. As shown in FIG. 14, FIG. 14 is a schematic diagram of a frame format in the scenario of FIG. The frame format in this scenario has no problem with the composition ratio of the number of uplink and downlink subframes. Specifically, each uplink subframe U includes only information related to UE1 or UE2, and the information corresponds to U1 or U2, respectively. Each downlink subframe D may sequentially include information on two UEs, namely D1 and D2. Method of inserting a SR S in this scenario is the same as method of inserting the SR S in the foregoing scenario, it will not be described detail here. Further, the insertion interval of the SRS may be adjusted according to the moving speed requirement.

  In scenario 3, there are multiple UEs in the beam, and each UE has an available secondary communication path. All UEs share downlink frequency band resources, and each UE exclusively uses uplink bandwidth resources. For example, in a frequency band with a bandwidth of 300 MHz, there are two UEs in the beam, the downlink of each UE occupies a bandwidth of 150 MHz, and the uplink of each UE occupies a bandwidth of 300 MHz To do. Thus, both UE capacity and system throughput capacity are significantly improved.

  In any implementation, the primary communication path may be controlled to be used for transmitting the uplink subframe of the transmitter indicated by the identifier, and the uplink subframe of the transmitter is a frequency division multiplexing scheme. Sent.

  The secondary communication path is controlled to be used to transmit the downlink subframe of the corresponding transmitter, and the downlink subframe of the transmitter is transmitted in a spatial multiplexing scheme, and the downlink subframe of the transmitter Exclusively occupies the bandwidth resources developed in the entire area, and the uplink subframe and the downlink subframe of the transmitter have different formats.

  Specifically, as shown in FIG. 15, FIG. 15 is a schematic diagram of another type of resource allocation in the scenario of FIG. The downlinks of UE1 and UE2 in the beam on the primary communication path are distinguished by a space division scheme, and the uplinks of two UEs are distinguished by a frequency division scheme.

  Specifically, the primary communication path may be controlled to be used only for uplink subframe transmission, and the secondary communication path may be used only for downlink transmission. The uplink and downlink frame formats of each UE are different and independent of each other. As shown in FIG. 16, FIG. 16 is a schematic diagram of another frame format in the scenario of FIG. Each downlink subframe D includes only information about UE1 or UE2, which corresponds to D1 or D2, respectively, and each uplink subframe U sequentially includes information about two UEs, namely U1 or U2. .

  In scenario 3, there are multiple UEs in the beam, and each UE has an available secondary communication path. All UEs share uplink frequency band resources, and each UE exclusively uses downlink bandwidth resources. For example, in a frequency band with a bandwidth of 300 MHz, there are two UEs in the beam, the uplink of each UE occupies a bandwidth of 150 MHz, and the downlink of each UE occupies a bandwidth of 300 MHz To do. Thus, both UE capacity and system throughput capacity are significantly improved.

  Scenario 4: When there is one identifier of a transmitter that communicates using the primary communication path and the transmitter indicated by the identifier has a corresponding secondary communication path, the uplink subframe and the downlink subframe of the transmitter The uplink subframe and the downlink subframe have different formats, and the transmitter occupies the bandwidth resources developed over the entire area.

  Specifically, referring to FIG. 17, FIG. 17 is a schematic diagram of still another communication scenario according to an embodiment of the present invention. As shown in FIG. 17, in this scenario, there is only one transmitter using the primary communication path, that is, there is only one UE in the beam corresponding to the primary communication path, that is, UE1, and the UE uses Has a possible secondary communication path.

  Further, as shown in FIG. 18, FIG. 18 is a schematic diagram of resource allocation in the scenario of FIG. Specifically, the UEs in the beam on the primary communication path may exclusively occupy those deployed in the entire area, and the uplink and the downlink are distinguished by the space division method.

Specifically, the primary communication path may be controlled to be used only for downlink subframe transmission, and the secondary communication path may be used only for uplink transmission, or the primary communication path May be controlled to be used only for uplink subframe transmission and the secondary communication path may be used only for downlink transmission. The uplink and downlink frame formats are different and independent of each other. As shown in FIG. 19, FIG. 19 is a schematic diagram of a corresponding frame format in the scenario of FIG. The frame format has no problem with the composition ratio of the number of uplink and downlink subframes. Specifically, each uplink subframe U1 and each downlink subframe D1 includes only information on the UE. Method of inserting a SR S in this scenario is the same as method of inserting the SR S in the foregoing scenario, it will not be described detail here. Further, the insertion interval of the SRS may be adjusted according to the moving speed requirement.

  In scenario 4, there is only one UE in the beam, the UE has an available secondary communication path, and the UE uses bandwidth resources exclusively. For example, in a frequency band having a bandwidth of 300 MHz, the UE occupies a bandwidth of 300 MHz, and the 300 MHz bandwidth may be supported in both uplink and downlink. Therefore, the UE capacity is significantly improved.

  Scenario 5: There are at least two identifiers of a transmitter that communicates using a primary communication path, the number of secondary communication paths is greater than zero, and the number of secondary communication paths is less than the number of identifiers.

  Specifically, referring to FIG. 20, FIG. 20 is a schematic diagram of still another communication scenario according to an embodiment of the present invention. As shown in FIG. 20, in this scenario, there are a plurality of transmitters sharing the primary communication path, that is, there are a plurality of transmitters in the beam corresponding to the primary communication path. In the specific example of FIG. 20, two UEs, that is, UE1 and UE2, exist in the beam corresponding to the primary communication path, and only the UE1 has a secondary communication path that can be used.

  In any implementation, the primary communication path may be controlled to be used to transmit the transmitter downlink subframe, where the transmitter downlink subframe is transmitted in a frequency division multiplexing manner, The transmitter includes a first transmitter that does not have a secondary communication path, that is, UE2, and a second transmitter that has a secondary communication path, that is, UE1.

  The primary communication path is controlled to be used for transmitting the uplink subframe of the first transmitter, and the uplink subframe of the first transmitter is transmitted by frequency division multiplexing, The uplink and downlink subframes of the transmitters are transmitted by time division multiplexing.

  The secondary communication path is controlled to be used to transmit the uplink subframe of the second transmitter, the uplink subframe of the second transmitter is transmitted in a spatial multiplexing scheme, The format of the uplink subframe and the downlink subframe of the transmitter are different.

  Specifically, as shown in FIG. 21, FIG. 21 is a schematic diagram of resource allocation in the scenario of FIG. Specifically, the downlink of UE1 and UE2 in the beam on the primary communication path is distinguished by the frequency division scheme, the uplink and downlink of UE2 are distinguished by the time division scheme, and the uplink and downlink of UE1 The links are distinguished by a space division method.

Specifically, the primary communication path may be controlled to be used only for downlink subframe transmission, and the secondary communication path may be used only for uplink subframe transmission. UE1 uplink and downlink frame formats are different and independent of each other, and UE2 uplink and downlink frame formats are the same. As shown in FIG. 22, FIG. 22 is a schematic diagram of a frame format in the scenario of FIG. Since UE1 and UE2 share the frame format of the downlink and downlink beam, when UE2 transmits uplink data in a time division multiplexing scheme, the bandwidth belonging to UE1 can only be in an idle state. The number of uplink and downlink subframes may be configured according to a preset configuration ratio, eg, 4: 4, and the configuration ratio may be adjusted according to the throughput of the uplink and downlink services. Since the uplink subframe U1 of UE1 can be transmitted by the spatial multiplexing method using the secondary communication path, the uplink subframe U1 of UE1 has an independent frame format. Specifically, each uplink subframe U1 transmitted using the secondary communication path includes only information related to UE1, and each downlink subframe D transmitted using the primary communication path includes information related to UE1 and Information on UE2 is sequentially included, that is, information on UE1 and information on UE2 correspond to D1 and D2, respectively. In each uplink subframe U, the frequency band belonging to UE1 is in an idle state and is represented by X in FIG. 22, and the frequency band belonging to UE2 includes information on UE2, that is, information on UE2 is U2 Corresponding to Method of inserting a SR S in this scenario is the same as method of inserting the SR S in the foregoing scenario, it will not be described detail here. The insertion interval of SRS may be adjusted according to travel speed requirements. Furthermore, the uplink data of UE2 may be further controlled to be transmitted in the uplink subframe and in the bandwidth of UE1 in the primary communication path using a specific technique.

  In scenario 5, there are multiple UEs in the beam, but each UE does not have an available secondary communication path. All UEs share downlink frequency band resources, and UEs having sub-optimal paths exclusively use uplink bandwidth resources. For example, in a frequency band having a bandwidth of 300 MHz, when the beam includes only UE1 and UE2, and only UE1 has a corresponding secondary communication path, the downlink of each UE occupies a bandwidth of 150 MHz, The uplink of UE2 occupies a bandwidth of 150 MHz, and the uplink of UE1 occupies a bandwidth of 300 MHz. Thus, both UE capacity and system throughput capacity are significantly improved.

  In any implementation, the primary communication path may be controlled to be used to transmit a transmitter uplink subframe, where the transmitter uplink subframe is transmitted in a frequency division multiplexing manner, The transmitter includes a first transmitter that does not have a secondary communication path, that is, UE2, and a second transmitter that has a secondary communication path, that is, UE1.

  The primary communication path is controlled to be used to transmit the downlink subframe of the first transmitter, and the downlink subframe of the first transmitter is transmitted by frequency division multiplexing, The uplink and downlink subframes of the transmitters are transmitted by time division multiplexing.

  The secondary communication path is controlled to be used to transmit the downlink subframe of the second transmitter, and the downlink subframe of the second transmitter is transmitted in a spatial multiplexing scheme, The format of the uplink subframe and the downlink subframe of the transmitter are different.

  Specifically, referring to FIG. 23, FIG. 23 is a schematic diagram of another type of resource allocation in the scenario shown in FIG. The uplinks of UE1 and UE2 in the beam on the primary communication path are distinguished by frequency division, the uplink and downlink of UE2 are distinguished by time division, and the uplink and downlink of UE1 are spatially divided. Differentiated by method.

Specifically, the primary communication path may be controlled to be used only for uplink subframe transmission, and the secondary communication path may be used only for downlink subframe transmission. UE1 uplink and downlink frame formats are different and independent of each other, and UE2 uplink and downlink frame formats are the same. As shown in FIG. 24, FIG. 24 is a schematic diagram of another frame format in the scenario of FIG. Since UE1 and UE2 share the frame format of the uplink and the uplink beam, when UE2 transmits downlink data by the time division multiplexing method, the bandwidth belonging to UE1 can be only in the idle state. The number of uplink and downlink subframes may be configured according to a preset configuration ratio, eg, 4: 4, and the configuration ratio may be adjusted according to the throughput of the uplink and downlink services. Since the downlink subframe D1 of UE1 can be transmitted by the spatial multiplexing method using the secondary communication path, the downlink subframe D1 of UE1 has an independent frame format. Specifically, each downlink subframe D transmitted using the secondary communication path includes only information regarding UE1, and each uplink subframe U transmitted using the primary communication path includes information regarding UE1. Information on UE2 is sequentially included, that is, information on UE1 and information on UE2 correspond to U1 and U2, respectively. In each downlink subframe D, the frequency band belonging to UE1, that is, X in FIG. 24 is in an idle state, and the frequency band belonging to UE2 includes information on UE2, that is, information on UE2 corresponds to D2. To do. Furthermore, the downlink data of UE2 may be further controlled to be transmitted in the downlink subframe and in the bandwidth of UE1 in the primary communication path using a specific technique.

  In the above scenario, there are multiple UEs in the beam, but each UE does not have an available secondary communication path. All UEs share uplink frequency band resources, and UEs having sub-optimal paths exclusively use downlink bandwidth resources. For example, in a frequency band having a bandwidth of 300 MHz, if the beam includes only UE1 and UE2, and only UE1 has a corresponding secondary communication path, the uplink of each UE occupies a bandwidth of 150 MHz, The downlink of UE2 occupies a bandwidth of 150 MHz, and the downlink of UE1 occupies a bandwidth of 300 MHz. Thus, both UE capacity and system throughput capacity are significantly improved.

  The frame format is determined according to a specific communication scenario, and the communication path (including the primary communication path and the corresponding secondary communication path) used for transmitting uplink and downlink subframes is determined for each UE. After that, it is possible to prepare for communication between the BS and the UE.

  After determining the primary communication path for communication with the UE that transmits the SRS according to the received SRS by implementing this embodiment of the present invention, the current BS further determines the secondary communication path for the UE, Extract the secondary communication path of another UE in the beam on the primary communication path, and communicate with each UE in the beam on the primary communication path based on the communication scenario established according to the primary communication path and the secondary communication path As a result, the data transmission throughput and data transmission efficiency of the system can be effectively improved.
